Procurement Notes
This component is officially classified as obsolete and is not recommended for new designs. Verification of current availability requires direct contact with the manufacturer or authorized distributors, as standard stock channels may no longer carry this part number. Designers should prioritize replacement options to ensure long-term supply chain stability.
Selection Notes
Select this component only for legacy system maintenance or repair where original specifications must be strictly maintained. For new projects, evaluate alternative glass passivated rectifiers that offer equivalent electrical ratings but are currently active in production. Ensure the replacement matches the DO-214AA footprint and thermal requirements.
Part Context
The CD214B-R31000 belongs to the CD214B-R series of glass passivated rectifiers designed by Bourns. This series targets the demand for smaller electronic components in portable electronics. The DO-214AA package allows for PCB real estate savings compared to competitive parts while maintaining high current handling capabilities.
Replacement Considerations
Official documentation states that recommended replacement products are available for this obsolete series. Users should consult the manufacturer's official discontinuation notice or datasheet for specific substitute part numbers suitable for their application requirements.
